Service Environment

1. Altitude: below 2000m;
2. Ambient air temperature :-25ºC~+40ºC;
3. Relative humidity: the daily average is not more than 95%, the monthly average is not more than 90%;
4. The surrounding air should be free from corrosive or flammable gases, water vapor and other obvious pollution;
5. No frequent violent shaking.

Main Features

1. The isolation switch adopts the double-column center opening and contact turn-in structure, which has the ability to automatically clean the contact and improve the contact reliability;
2. The contacts are made of new materials with high strength, high conductivity and high elasticity. By clamping the contact with the elastic force of the contact finger itself, the vicious cycle of decreasing the clamping force of the contact, increasing the contact resistance and aggravating the hair heat caused by spring rust and heat annealing is avoided.
3. The rotating part of the isolation switch is designed according to the requirements of maintenance-free. The rotating seat is designed as a sealed structure, water vapor, dust, harmful gases can not enter, so that the bearing, lithium molybdenum disulfide lithium grease will always work in a good environment, the bearing will never rust, the grease can not be lost, never dry, so that the operating torque of the isolation switch will not increase after long-term operation. Stainless steel shaft pin and oil-free self-lubricating bearing matching structure;
4. The steel parts are hot-dip galvanized to ensure that the isolation switch is flexible, lightweight, reliable and never rusted.
